Cardiovascular System Practice Exam
1. This heart condition is characterized by decreased cardiac output and tissue perfusion, which can lead to organ failure.
- A. Cardiogenic shock
- B. Myocardial infarction
- C. Endocarditis
- D. Pericarditis
Correct answer: A
Rationale: The correct answer is A: Cardiogenic shock. Cardiogenic shock is a severe condition characterized by the heart's inability to pump enough blood, leading to decreased cardiac output and tissue perfusion, which can result in organ failure. Choice B, Myocardial infarction, specifically refers to a blockage of blood flow to the heart muscle. Choices C and D, Endocarditis and Pericarditis, do not directly involve decreased cardiac output leading to organ failure, making them incorrect in the context of the symptoms described in the question.
2. What is a condition where the arteries that supply blood to the heart muscle become hardened and narrowed due to the buildup of plaque?
- A. Atherosclerosis
- B. Aneurysm
- C. Arrhythmia
- D. Peripheral artery disease
Correct answer: A
Rationale: Atherosclerosis is the correct answer. It is a condition characterized by the hardening and narrowing of arteries supplying blood to the heart due to plaque buildup. This condition increases the risk of heart attacks. Choice B, aneurysm, refers to a balloon-like bulge in an artery, not the hardening and narrowing of arteries. Choice C, arrhythmia, is an irregular heartbeat and not related to arterial hardening. Choice D, peripheral artery disease, involves the narrowing of arteries that supply blood to the limbs, not specifically to the heart.
3. Which medication is used to lower high blood pressure and reduce the risk of heart attacks and strokes?
- A. ACE inhibitor
- B. Beta-blocker
- C. Diuretic
- D. Calcium channel blocker
Correct answer: A
Rationale: The correct answer is an ACE inhibitor. ACE inhibitors are medications specifically designed to lower high blood pressure and reduce the risk of heart attacks, strokes, and other cardiovascular events. Beta-blockers, diuretics, and calcium channel blockers are also used to treat high blood pressure, but ACE inhibitors are particularly effective in reducing the risk of heart attacks and strokes.
4. What is a condition where a blood clot forms in a deep vein, usually in the legs, and can lead to serious complications if it travels to the lungs?
- A. Deep vein thrombosis (DVT)
- B. Pulmonary embolism
- C. Varicose veins
- D. Raynaud's disease
Correct answer: A
Rationale: The correct answer is A, Deep vein thrombosis (DVT). Deep vein thrombosis occurs when a blood clot forms in a deep vein, usually in the legs. If the clot dislodges and travels to the lungs, it can lead to a serious condition called a pulmonary embolism. Choice B, pulmonary embolism, is incorrect as it is the consequence of a DVT clot traveling to the lungs, not the initial condition. Choices C and D, varicose veins, and Raynaud's disease, respectively, are unrelated conditions to the formation of blood clots in deep veins.
5. Which type of lung cancer is strongly associated with exposure to asbestos?
- A. Mesothelioma
- B. Adenocarcinoma
- C. Squamous cell carcinoma
- D. Small cell lung cancer
Correct answer: A
Rationale: The correct answer is Mesothelioma. This type of lung cancer is indeed strongly associated with exposure to asbestos, affecting the lining of the lungs or abdomen. Adenocarcinoma, Squamous cell carcinoma, and Small cell lung cancer are not primarily linked to asbestos exposure, making them incorrect choices for this question.
